Superconductivity is a state of matter characterized by an electrical resistance of zero, typically at very low temperatures. Past studies have found that in various materials, this unique state is accompanied by unusual electron arrangements.

In some superconductors, for instance, electrons spontaneously align in a preferred direction, breaking a property known as rotational symmetry. This directional arrangement of electrons is also known as electronic nematicity.

Moreover, some superconductors also exhibit a strange metallicity. This is a phase characterized by unusual changes in a material’s electrical resistance, which cannot be explained by standard physical theories.
